Going too fast? Gods man, you call THAT fast? 
It's very doubtful that will be of any help in court. Go to court, plea guilty with explanation, and try to at least get the fine and points lowered a bit.
Just feel lucky, cause if you were to get pulled over for that speed in MD on a state highway.... you are going for a ride with bracelets on. They are REALLY cracking down hard on that here now. I found that out 2 years ago. I since learned to drive like an old man.
Good luck.
